Description

Technical Field

[0001] This utility model belongs to the field of dental equipment technology, and in particular relates to a dental handpiece drying holder. Background Technology

[0002] Dental handpieces are commonly used diagnostic and treatment instruments in dentistry, with high usage and turnover rates. Due to their delicate and complex structure and small lumen, drying them is challenging. Incomplete drying can easily lead to the formation of oil sacs. Studies have shown that oil sacs can affect steam penetration, resulting in incomplete sterilization. Incomplete sterilization not only requires re-sterilization, wasting time, but also endangers patient safety and seriously disrupts normal medical procedures.

[0003] Therefore, to ensure the dental handpiece is completely dry and achieves the required sterilization effect, various dental handpiece drying stands are currently available on the market. These stands allow the handpiece to be placed upright to control oil and drain water. For example, there is a product with authorization notification number CN 213066857. U's utility model patent discloses a dental handpiece drying rack. The drying rack has a rectangular frame structure, specifically including a support unit and an oil absorption unit. By setting the support unit, the dental handpiece is kept in a vertical position, so that water or oil inside the dental handpiece will drip downwards under the action of gravity, and will not remain inside the dental handpiece to affect the drying effect. The oil absorption unit at the bottom can collect the dripping water and oil, preventing water and oil from dripping everywhere and affecting the environment. Although this drying rack solves the shortcomings of the existing ones, its structure is fixed and monotonous. Not only can the support unit not be replaced as needed, but the support hole (first through hole 111) on the support unit has a fixed diameter, which can only be used for a certain type of handpiece with a fixed diameter. Specifically, for the purpose of universality, the hole diameter is usually set slightly larger than that of high-speed handpieces (the diameter is generally 16-18mm). This causes low-speed handpieces with a smaller diameter (about 10-12mm in diameter) to wobble in the support hole and collide with the hole wall, especially during transportation.

[0004] Based on the above analysis, this application designs a dental handpiece drying holder. Utility Model Content

[0005] The purpose of this invention is to provide a dental handpiece drying holder to solve the problem of low compatibility of existing handpiece holders.

[0006] To address the aforementioned issues, this solution provides a dental handpiece drying bracket: comprising an oil-receiving base, with a support unit mounted above the oil-receiving base via a support frame. The support unit includes a fixed base plate and a movable base plate stacked vertically. The fixed base plate is located on a side close to the oil-receiving base, and a first hole and a second hole coaxially arranged on the surfaces of the fixed base plate and the movable base plate, respectively. Simultaneously, a flexible pad is provided on at least one of the fixed base plate and the movable base plate, and a third hole is provided on the flexible pad. The third hole is coaxially arranged with the first hole and the second hole, and its diameter is at least smaller than the maximum diameter of the first hole and the second hole.

[0007] As a preferred embodiment of this application: the support frame includes multiple columns and an adjusting beam. Each of the multiple columns is provided with multiple adjusting holes arranged along its axial direction. The adjusting beam can be inserted into the adjusting holes of two adjacent columns to form an adjusting frame. The moving base plate is supported by the adjusting frame and the distance between it and the fixed base plate can be adjusted.

[0008] As a preferred embodiment of this application: the adjusting beam includes a crossbar section and a bent end, and at least the diameter of the bent end is adapted to the adjusting hole.

[0009] As a preferred embodiment of this application: the plurality of adjustment holes are connected by a guide groove, the width of which is smaller than the diameter of the adjustment hole; at the same time, the bent end includes a waist and a locking block, the size of which is smaller than the size of the guide groove, and the size of which is adapted to the adjustment hole.

[0010] As a candidate solution of this application: the fixed substrate and the moving substrate have corresponding shapes and are both circular, square or polygonal. The fixed substrate and the moving substrate are provided with mounting holes on their surfaces, through which the fixed substrate and the moving substrate can be respectively mounted on the column.

[0011] As a preferred embodiment of this application: the oil receiving base is provided with an oil receiving groove, which is a sunken groove located directly below the first and second openings, and oil-absorbing paper is laid in the oil receiving groove.

[0012] As a preferred embodiment of this application: the diameter of the second orifice is larger than the diameter of the first orifice, wherein the diameter of the first orifice is greater than or equal to 1 cm, and the space of the second orifice is greater than or equal to 2 cm.

[0013] As a preferred embodiment of this application: the flexible pad is selected from any one of medical rubber, medical latex and medical silicone that is resistant to moisture and high temperature, and the size of the flexible pad corresponds to the fixed substrate and the moving substrate.

[0014] As a preferred embodiment of this application, the oil receiving base and the support unit are made of stainless steel.

[0015] As a preferred embodiment of this application, the bottom of the oil receiving box is provided with an anti-slip pad.

[0016] Compared with existing technologies, the advantages of this application are:

[0017] This solution improves upon existing designs. The support unit of the bracket includes a fixed base plate and a movable base plate, with the movable base plate positioned above the fixed base plate. This allows for flexible replacement of the movable base plate as needed, facilitating its maintenance and replacement. Furthermore, a flexible pad is placed on one of the fixed or movable base plates. The diameter of a third opening in this flexible pad is smaller than the maximum diameter of the first and second openings. The material of this third opening determines its deformation range, thereby limiting and protecting dental handpieces of different diameters. This prevents direct contact between the handpiece and the support unit, avoiding damage and extending the handpiece's lifespan. Simultaneously, it is compatible with both small-diameter, low-speed handpieces and large-diameter, high-speed handpieces, improving the bracket's adaptability and practicality. In summary, this bracket design not only has a simple structure and low cost but also offers higher adaptability, flexibility, and stability, possessing significant practical and market value.

Detailed Implementation

[0027] The present invention will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be emphasized that the following description is merely exemplary and not intended to limit the scope and application of the present invention.

[0028] This embodiment provides a dental handpiece drying bracket, including an oil-receiving base 10. A support unit 20 is mounted above the oil-receiving base 10 via a support frame 30. The support unit 20 includes a fixed base plate 21 and a movable base plate 22 stacked vertically. As the names suggest, the fixed base plate 21 is a fixed plate fixed to the support frame 30, and the movable base plate 22 is a movable plate that can move relative to the support frame 30. This allows adjustment of the distance between the movable base plate 22 and the fixed base plate 21 to accommodate handpieces of different heights. The movable base plate 22 can also be replaced as needed. In this embodiment, the fixed base plate 21 supports the handpiece, and the movable base plate 22 straightens the handpiece; that is, the movable base plate 22 and the fixed base plate 21 work together to keep the handpiece in a vertical position. In this embodiment, the fixed base plate 21 and the movable base plate 22 have corresponding shapes and are either circular, square, or polygonal. Figure 1-2The figure shows a schematic diagram of the overall structure of two preferred simplified brackets provided in this embodiment. As shown in the figure, the fixed base plate 21 is disposed on the side near the oil receiving base 10, and the fixed base plate 21 and the movable base plate 22 are respectively provided with a first hole 211 and a second hole 221 arranged coaxially. At the same time, a flexible pad 23 is provided on at least one of the fixed base plate 21 and the movable base plate 22. The flexible pad 23 is provided with a third hole 231. The third hole 231 is coaxially arranged with the first hole 211 and the second hole 221, and its diameter is at least smaller than the maximum diameter of the first hole 211 and the second hole 221 to ensure that a buffer washer is formed at the hole. The buffer washer provides a buffering force for the mobile phone installed in the hole to prevent it from directly hitting the hole wall. In this embodiment, based on the functions of the fixed substrate 21 and the moving substrate 22, the diameter of the first aperture 211 on the fixed substrate 21 should be smaller than the minimum diameter of the mobile phone, preferably 1 cm in this embodiment, to ensure that the mobile phone can be supported while ensuring that oil and water can fall off. The diameter of the second aperture 221 on the moving substrate 22 should be larger than the maximum diameter of the mobile phone, preferably 2 cm in this embodiment, so that the mobile phone can pass through the second aperture 221 and be straightened by the inner wall of the second aperture 221. In this embodiment, it is preferable that flexible pads 23 are provided on both the fixed substrate 21 and the moving substrate 22, and the diameter of the third aperture 231 on the flexible pad 23 is smaller than the second aperture 221 and equal to or slightly larger than the diameter of the first aperture 211. Figure 6-7 As shown, a protective washer is formed at the second opening 221 and a support washer is formed at the first opening 211. This effectively plays a buffering and protective role, effectively reducing the collision and friction generated when the dental handpiece is in direct contact with the bracket, reducing the risk of wear and damage to the handpiece surface, and also absorbing the vibration generated when the handpiece is placed or removed to a certain extent, protecting the internal precision components of the handpiece.

[0029] In this embodiment, the oil receiving base 10, support frame 30 and support unit 20 are preferably made of stainless steel, which satisfies the high temperature resistance requirement and is relatively lightweight; the flexible pad 23 is preferably made of medical rubber that is resistant to high temperature and humidity, either medical latex or medical silicone. In this embodiment, it is preferably EPDM rubber, which has a thickness of 2-5mm and a size that corresponds to the fixed base plate 21 and the moving base plate 22.

[0030] like Figure 3As shown in Figure 5, this is a schematic diagram of the overall structure of the support frame 30 provided in this embodiment. The support frame 30 includes multiple columns 31 and adjusting beams 32. The multiple columns 31 are vertically fixed in the oil receiving base 10. In this embodiment, the number of columns 31 is selected according to actual needs. To ensure stability, 3-4 columns can be selected. In this embodiment, it is preferred that when the fixed base plate 21 and the moving base plate 22 are circular or polygonal, the number of columns 31 is 3. The 3 columns 31 are equidistantly arranged in a ring. When they are square, the number of columns 31 is 4. The columns 31 are respectively provided with multiple adjusting holes 311 arranged along their axial direction. The adjusting beams 32 can be inserted into the adjusting holes 311 of two adjacent columns 31 to form an adjusting frame. The moving base plate 22 is supported by the adjusting frame and the distance between it and the fixed base plate 21 can be adjusted. Specifically, as needed, the adjusting beams 32 can be inserted into the adjusting holes 311 of different heights of two adjacent columns 31 to adjust the height of the adjusting frame, thereby adjusting the height of the moving base plate 22.

[0031] As a preferred embodiment, the adjusting beam 32 includes a crossbar section 321 and a bent end. At least the diameter of the bent end is adapted to the adjusting hole 311. In this embodiment, the adjusting beam 32 is a bent tube structure with both ends in an L-shape or U-shape, consisting of the crossbar section 321 and the bent end. After the bent end is inserted into the adjusting hole 311, the crossbar section 321 and the column 31 are perpendicular to each other.

[0032] As a preferred embodiment, to facilitate adjustment and prevent the adjusting beam 32 from separating from the column 31, the multiple adjusting holes 311 in this embodiment are connected by a guide groove 312. The width of the guide groove 312 is smaller than the diameter of the adjusting hole 311. Simultaneously, the bent end includes a waist portion 322 and a locking portion 323. The size of the waist portion 322 is smaller than the size of the guide groove 312, and the size of the locking portion 323 is adapted to the adjusting hole 311. Figure 4 As shown.

[0033] During specific adjustment, push the adjusting beam 32 inward to disengage the locking block 323 at the bent end from the adjusting hole 311 and ensure that the waist part 322 is engaged in the guide groove 312. At this time, the waist part 322 can move within the guide groove 312 to adjust the adjusting beam 32 upward or downward. When adjusted to the position of the adjusting hole 311 at the specified height, pull the adjusting beam 32 outward to engage the locking block 323 in the adjusting hole 311, thus completing one height adjustment. Compared with traditional bolts or clips, this structure not only has high adjustment efficiency but also fewer parts, reducing the problem of missing parts that could affect the normal use of the support frame 30.

[0034] As a preferred embodiment, mounting holes are provided on the surfaces of both the fixed substrate 21 and the moving substrate 22. The fixed substrate 21 and the moving substrate 22 can be mounted on the column 31 through these mounting holes. Of course, if necessary, slots can be provided on the side walls of the moving substrate 22 and the fixed substrate 21 as mounting holes.

[0035] As a preferred embodiment, the oil receiving base 10 is provided with an oil receiving groove 11, such as... Figure 6 As shown, the oil receiving groove 11 is a recessed groove set on the base, located directly below the first opening 211 and the second opening 221. The oil receiving groove 11 is lined with oil-absorbing paper to absorb the oil and water dripping from the mobile phone. Understandably, in order to improve stability, the oil receiving base 10 can be designed with counterweights if necessary.

[0036] In this embodiment, the depth of the oil receiving groove 11 is preferably about 1 cm, which is sufficient to accommodate the oil-absorbing paper, and the thickness of the oil-absorbing paper is 0.1 mm.

[0037] To improve the stability of the simple support, it is preferable to provide an anti-slip pad 12 at the bottom of the oil receiving box. The anti-slip pad 12 is made of the same material as the flexible pad 23.

[0038] The specific operating principle of this embodiment includes:

[0039] Before use, adjust the height of the moving substrate 22 relative to the fixed substrate 21 according to the height of the mobile phone to be dried using the adjustment frame, and ensure that the first hole 211 and the second hole 221 on the fixed substrate 21 and the moving substrate 22 correspond.

[0040] In use, each mobile phone to be dried is passed through the first opening 211 and brought into contact with the second opening 221. Understandably, due to the design of the flexible pad 23, the mobile phone must overcome the elasticity of the third opening 231 when passing through the first opening 211. That is, the mobile phone is buffered and limited by the flexible pad 23 and the third opening 231 within the first opening 211, which not only secures it within the first opening 211 but also prevents it from directly contacting the stainless steel. At the same time, the flexible pad 23 located at the second opening 221 acts as a buffer pad to cushion and support the end of the mobile phone. Under the coordinated action of the first opening 211 and the second opening 221, the mobile phone is placed vertically in the bracket. After the mobile phones are placed, the simple bracket is moved to the designated equipment for high-temperature sterilization. Understandably, since the bracket of this solution has an open structure, there is no problem of steam obstruction, which effectively improves the steam sterilization efficiency.

[0041] In summary, this solution improves upon existing solutions. The support unit 20 of the bracket includes a fixed base plate 21 and a movable base plate 22, with the movable base plate 22 positioned above the fixed base plate 21. This allows for flexible replacement of the movable base plate 22 as needed, facilitating its maintenance and replacement. Furthermore, a flexible pad 23 is provided on one of the fixed base plate 21 or the movable base plate 22. The diameter of the third aperture 231 on this flexible pad 23 is larger than the diameter of the first aperture 211 but smaller than the maximum diameter of the second aperture 221. The material of the third aperture 231 determines its deformation range, thereby limiting and protecting dental handpieces of different diameters. This prevents direct contact between the handpiece and the support unit 20, thus avoiding damage and extending the handpiece's lifespan. Simultaneously, it can accommodate both small-diameter, low-speed handpieces and large-diameter, high-speed handpieces, improving the bracket's adaptability and practicality. Therefore, this embodiment of the bracket not only has a simple structure and low cost but also offers higher adaptability, flexibility, and stability, possessing significant practical and market value.

[0042] The above descriptions are merely embodiments of this utility model, and common knowledge regarding specific structures and characteristics is not elaborated upon here. It should be noted that those skilled in the art can make various improvements without departing from this utility model, and these improvements should also be considered within the scope of protection of this utility model. These improvements will not affect the effectiveness of the implementation of this utility model or the practicality of the patent. The scope of protection claimed in this application should be determined by the content of the claims, and the specific embodiments described in the specification can be used to interpret the content of the claims.
